Which two pieces of information does a Citrix Engineer need in order to join additional StoreFront servers to an existing server group? (Choose two.)

The name of the existing StoreFront server is required so the joining server can locate and communicate with the primary server in the group during the join process.

The base URL of the StoreFront deployment is not a required input when joining a server to an existing group; it is already part of the replicated configuration.

There is no 'security key' input in the StoreFront server group join workflow; the authorization mechanism uses an authentication code, not a separate security key.

The authentication code is a time-limited token generated from the existing StoreFront server that authorizes the new server to join the group, preventing unauthorized servers from being added.

Local administrator access is needed on the server being joined, not remote administrative access to the original StoreFront server.
